LOZENGE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 273,518, dated March 6, 1883'. Application filed October `13, 1881. (No modeh) To all whom t may concern:

Be it known` that I, CHARLES H. HALL, of Chicago, in the county of Cook and State ot' Illinois, have inventedcertain new and useful Improvements in Lozenge-Machines; and I do hereby declare the following to be a full,

clear, and exact description thereof, that will,

enable others to construct and operate the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, forming a 'part ot' this specification. Y

This invention relates to improvements in lozen ge-machines; and it consistsin the parts which will be hereinafter described,and pointed out in the claims.

1n the accompanying drawings, Figure 1 is a view of the cutting mechanism proper, looking outward. Fig. 2 is a vertical longitudinal section. Fig. 3 is a side elevation. rFig. 4 is a vertical section of one of the cutters and inclosed pistons, showing the relation of these parts. Fig. 5 is a face view of the lower end of the piston and cutter; Fig. 6, a top view of the cutting apparatus. Fig. 7 is a detached view of the bowed or bent crank-shaft, imparting a reciprocating motion tothe cutter-frame.

Referring to the drawings, A A represent the side pieces, A2 the back end piece, and A3 the front cross-piece, composing the framework supporting the operating mechanism, and yA4 A5 A6 are tie-rods securing the framework together. The upper front end of the supporting-frame is cut away at an oblique angle, so as to permit of the cutting mechanism being set on a vertical incline, as shown in Figs. 2 and 3 of the drawings.

The traveling guide-rods B B are placed on the inside of the frame-pieces A A', and are secured in place by the bearing box or boxes B2, as shown in Fig. 2, the companion guiderod-on the opposite inside being secured in the same manner, but not shown in the drawings, as it is a mere duplication. These guide-rods pass up through and have bearings in the cutting bed-pieces B3 B4, the ends of the lower piece being rigidly secured to the top of the frame, as shown in Fig. l of the drawings, while the upper or third piece, B5, is composed of wood and forms the'cuttingsurface proper. The guide-rods also pass through the ends of the perforated'clearingplate C, which is secured in a stationary position to the cross-piece B4 by means ot' the srewsa, of which there are four, in line with and on the frontand rear sides of the guiderods. The clearing-plate C is perforated, so as to admit the series of cutters C2. Said perforations are of greater diameter at the top than at their bottom or under side, so as to present a sharp scraping-edge. (Shown in dotted line,

Fig. l.) By this means any material that might adhere to the cutters would be removed on the upward stroke-z'. c., the clearing-plate operates as a scraper for the sides of the cutters. 0n and near the upper ends ot' the guiderods is placed the cutter-bar C', carrying the series'of .cutters C2. This cutter-bar is vertically adjustable on the guide-rods by means ot' the screw-nuts a a' a. a', engaging with the threaded ends of the guide-rods. The series of cutters illustrated are cylindrical in form, but may be of any desired shape thattaste or practical workin g should require, the form of the pistons corresponding thereto, thus enabling the same machine to produce lozenges of any desired form by removing one series ot' cutters and substituting others of a different shape. The lower interior cutting-surface of the cutters shown is of the greatest diameter at the extreme end, gradually narrowing'.

inward to a short distance from the edge, while the exterior lower end is ot' a less diameter than'the immediate upper part ofthe exterior surface of the cutter, th`us forming a wedge-shaped cutting-edge, which readily frees itself from the sheet of paste or dough, and produces a lozenge with a regular slope or bevel from'the base to the crown.

The cross-bar C3 is located on the guide-rods above the cutter-bar, and is adjustably secured in relation thereto by means of the tap-bolts ai a3. This cross-bar C3 is perforated for the passage of the series of stems or spindles a, to the lower ends of which are attached the piston-heads C4, traveling on the inside of the cutters. This cross-bar C3 serves the purpose of gagin'g the thickness of the lozenge or confection-that is, by moving the bar up a thicker out is produced, andvdown a thinner one, this IOO adjustment changing the distance of the piston from the lower edge of the cutter. The piston stem or stems are enlarged at a point immediately above the upper ends of the pisto,ns,forming the annular shouldera5, as shown in Fig. 4, which comes in contact with and has a bearin g against the under side of the crossbar G3, serving as a stop to gage the travel of the pistons, and, in connection with the crosshar G5, these parts are so arranged as to conveniently produce alozenge ofthe desired thickness. On the upper ends of the piston-stems, and above thecross-bar G5, are placed the spiral springs a5, which serve to return the pistons to their normal position after they have served the function of expelling the lozenges from the cutters. Fig. l shows the cutting apparatus at the upper end ot' the stroke, the ends of the piston-stems coming in contact with the under side of the stop-bar C5, forcing the pistons ldownward and expelling the lozenges from the cutters, the dotted lines lepresentin g the cutters at the lower end of the stroke in contact with the cutting-bed. The stop-bar O is adjustably secured to the bolts or studs D D',

which project upward from the frame. This stop-bar not only causes the pistons to descend in the cutters, but also gages the distance they are to travel on the downstroke so as to come tlnsh with the cutting-edge,or made to project a little below, as shown in Fig. l of the drawl:he short bars D2 D3 are supported on the bolts D D', and are placed underneath at right angles to the stop-bar C5. The outer ends of the bars D2 D3 are perforated for the reception of and provide bearings for the ends of the rock-shaft- D, to which are rigidly secured the upper ends of the connecting-arms b b'. The lower ends ot' these arms are pivoted to the sides of the receiving-tray D5. The outer ends ot' the cani-arms b2 b3 are rigidly attached to the rock-shaft D4, the opposite ends being loose, projectinginward and downward atabout the angle shown in Fig. 2 of the drawings. As the cutting mechanism moves upward, the top side of the cross-bar G3 comes in contact with the loose ends of the cam-arms b2 b3, forcing the same in an upward direction, causing the rock-shaft D5 to rotate, and, through the medium ot` the connecting-arms b b', moves inward and upward the tray D5 at the proper time to receive the goods forced from the cutters by the pistons, and as the cutters start on the downstroke the receiving-tray gravitates to its normal position, this receiving-tray having an intermittent reciprocating movement. Theinneredge ofthe receiving-tray is provided withv the elongated slots b4 b5 for the purpose of clearing the guide-rods B B'. The inner ends of the bars D2 D3 support the ends of the stationary rod d, which provides a bearing for the upper ends of the connecting-arms d' d2,

the lower ends being pivoted tothe receiving-tray D5 and support the inner end of the same. One end of the stops d3 L4 are secured to the lower part of the arms d' d2, while the opposite ends are turned at right angles to form a bearing for contact with the bolts D D', which serve the purpose of preventing the .receiving-tray from gravitatin g beyond a certain point as it returns to a normal position.

A reciprocating movement is imparted to the cutting mechanism through the medium of the cross-head E, having connection with the guide-rods B B', the rod E', and the bent or bowed crank-shaft E2, as shown in Figs. 1 and 7 ot'the drawings. The crank-shaftisjournaled in the side pieces of the main frame-work, and an outer projecting end carries the crank-wheel E5, which is provided with the pin E', to which is attached one cnd of the connecting-rod F, the upper end connecting with the rocker-arm F', attached to the roller F2. by which motion is transmitted to the crank E3.

The graduating-rollers F2 F3 are common to this class of machines. A general description will therefore be omitted in this case.

The endless apron F4 carries the sheet of paste or dough to the cutters, traveling over the rollers Fz F5.

The face of the pistons bearing on the lozenges may be perfectly plain or be provided with letters, words, or characters of ornamental desigmthese contigurations beingraised above the immediate surface of the pistons or indented, imparting a corresponding impression to the goods.

This machine is adapted to be employed in the manufacture of crackers and the various styles of confections.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. The cutters C2, pistons C", stems a4, having shoulder-bearings a5, springs a5, cutterbar C', and adjustable stop-bar C5, in combination with the cross-bar C3, vertically adjustable on rods B B' by bolts a2 a3, whereby alozenge of the desired thickness is produced, substantially as described, and for the purposes set forth.

2. The combination, with the receiving-tray D5, of 'the arms b b', the rock-shaft Dfi, the camarms b2 b5, and the cross-bar G3, whereby the tray D5 is moved under the cutters to receive the goods, substantially as described.

3. lThe combination, with the receiving-tray D5, of the arms d' d2, the stops d5 d", and the bolts D D', which serve to prevent the tray moving beyond a certain line on the inclined plane, substantially as described.
